For 26 ac I think the word 'round ' is superfluous.
In crossword terms it would indicate that 'Boatman' went round 'answe'r - which is not how the answer works (as I have it). So take round out and it works as a straight clue.
That's what I thought all along, but several people here seem to think there are NO exceptions!
A propos: where's the theme word in 1a? Surely not the answer THEN the theme word? I'm still puzzled!
